Discussion

Graphic symbols for this referent show quite some variation concerning the image content, from rather abstract map symbols to quite detailed traffic sign symbols. While some renderings just show the water falling and the water below, others rely on additional shapes to indicate some kind of landscape.

In our research we discovered that there is only very limited test data available for the referent Waterfall:

Fiori (2008) examined a map symbol almost identical to the pictogram labeled as DER in the table above. 83.4 % of the responses in a Comprehension Test were classified as correct, indicating the pictogram used for traffic signs in Brazil is well comprehensible.

For the more abstract variants we expect insufficient comprehensibility, especially if not enough context information is available.

Recommendations

We advocate to conduct a study including a Comprehension Test comparing all the concepts above to determine the image content working best. Furthermore we suggest to develop other variants with a strong focus on keeping minimum detail large enough to ensure legibility, but still providing enough information even in applications with insufficient context.
